Holidaygal,
i didnt ask.. in any case, prof doesnt give hypothetical answers, so ask him, he might also tell u he doesnt have an answer.. my guess is that the eggs still small during retrieval? i was stimulated for 14 days, and follicle size is good (16 to 18mm), so i feel that follicle size does not equate to egg size? i also not sure... maybe over suppressed in long protocol?
Prof did console me that the results already not the worst, at least there were 2 good embryos for me to transfer, and he suggested a short protocol for me to try for my 2nd round.. maybe u can ask him how come he gave u 2 long protocols?
